SP → SP · SP-330 (Anhanguera)
Coming back from Ribeirão Preto, SP, to Guarulhos, SP, the return leg also clocks roughly 371 km (231 miles) typically along SP-330 (Anhanguera), but the traffic picture shifts considerably compared with the outbound segment. Ribeirão Preto, the capital nacional do agronegócio sucroalcooleiro, fades behind the wheel while the vehicle pushes back toward Guarulhos, the segunda maior cidade paulista e sede do principal aeroporto internacional do Brasil, often after a full day of meetings, site visits, or prospecting calls. Plan 4h 22m plus a generous buffer against evening congestion, particularly on Fridays, holiday eves, or after major sporting events. Driver fatigue is the dominant concern returning home; mandatory rest breaks every two hours are non-negotiable. Fuel spend on the return stays near R$ 205,57 for 33.7 liters (8.9 gallons). The corresponding reimbursement on the way back reaches R$ 408,10 at R$ 1,10/km. Combine both legs on a single Clara receipt to document the full round-trip cleanly, with separate timestamps for transparent audit defense. For the US professional driving the 371 km (231 mi) between Ribeirão Preto and Guarulhos, reimbursement of R$ 408,10 stays non-taxable to the employee when the employer follows an accountable plan under Treas. Reg. §1.62-2 and reimburses at or below the IRS standard mileage rate. US employers generally reimburse at the IRS standard mileage rate so the payment stays non-taxable to the employee under Pub. 463. Keep the IRS-compliant expense report (Form 1040 Schedule C, line 9) alongside the fuel receipt from any EIA-tracked retail station network pump used along the leg; Internal Revenue Service (IRS) examiners pull contemporaneous mileage logs first when auditing Schedule C unreimbursed business expenses, and the Ribeirão Preto→Guarulhos corridor must show date, business purpose, and odometer readings.
